Abstract: We perform three dimensional molecular dynamics simulations of cohesive
granular particles under a plane shear. From the simulations, we found that the
granular temperature of the system abruptly decreases to zero after reaching
the critical temperature, where the characteristic time $t_{\rm cl}$ is
approximately represented by $t_{\rm cl} \propto (\zeta-\zeta_{\rm
cr})^{-\beta}$ with the dissipation rate $\zeta$, the critical dissipation rate
$\zeta_{\rm cr}$ and the exponent $\beta \simeq 0.8$. We also found that there
exist a variety types of clusters depending on the initial density and the
dissipation rate.
